no sir.
since you have managed a long legal battle and involved so many depts caused annoyance (to baboo class), i would not suggest to play wrong cards in excitement.

is there any documentation upon compromise for handing taking over of vehicle?
a documentary evidence with signatures of witnesses specially the ETO Mardan document etc mentioning Faisalabad FIR no / case no etc ?
without any such document i'd not suggest to move an inch forward for FIR cancellation.
way forward i can explain after you share the complete story.
i see something DARK for you & the vehicle in long shot if everything is based on talk & compromise without any documentation. bhai chara rishtaydari musalman bhai ghalti ho gai maafi etc etc
